Abstract: The impact of the individual traveler’s micro behavior on the macro characteristics of the transportation network. was discassed. The traveller types and their route selection rule were redesigned according to different traffic information received by them. The impact rate of individual traveller’s action on traffic network efficiency was simulated by considering traffic network evaluation model including such factors as need for transport, time and cost .The simulation results show: the timely supply of traffic information and traveller’s learning ability of traffic information can overall improve the running efficiency of road network. Of similar travelling scale, the traveller with learning behavior causes minor influence to the traffic network efficiency which is stable. In case of sufficient traffic information supplied, the number of information learned travellers is influenced by the capacity of road network.

摘要： 为有效反映城市道路网络中出行者的个体微观行为对网络宏观特征的影响，根据出行个体对交通信息的接受情况不同对出行者的类型、及其路径选择规则进行重新设计，结合兼顾考虑交通需求、时间费用和交通流量的交通网络效率评价模型，利用仿真技术，模拟出行者个体行为对交通网络效率的影响。仿真结果显示：交通信息的及时供给和出行者对交通信息的学习能力，整体上会有效提升路网的运行效率；在相同出行规模情形下，具有学习行为的出行者交通网络效率稳定且波动小；在交通信息供给充分的条件下,信息学习出行者的规模受到路网的承载能力的影响。
